Alexandru Objelean commented on WICKET-995:
-------------------------------------------
I agree with Alastair. A developer cannot confused by something that is
generated automatically. Nobody really cares if the generated markup ID is
"quantity1", "quantity_1", "quantity.1" or "quantity-1".
Also, it's not a jquery bug at all. The '.' character is interpreted as a css
class. So, the $("#quantity.noOfUnits1232") translates in element with ID
"quantity" and css class "noOfUnits1232".
> getMarkupId generates ID which contains special characters which should be
> escaped or replaced

> Key: WICKET-995
> URL: https://issues.apache.org/jira/browse/WICKET-995
> Project: Wicket
> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.3.0-beta3
> Reporter: Alexandru Objelean
> Assignee: Igor Vaynberg
> Fix For: 1.3.0-beta4
>
>
> This is about how wicket generates dynamically markupID.
> I have, for instance, the following markup component:
> <input wicket:id="quantity.noOfUnits" />
> The generated markupId for this component looks like the following:
> quantity.noOfUnits1232 .
> I suggest to escape any css valid specifiers from the generated markupId, by
> replacing them with something else (for instance '_' character).
> The problem appear when I am trying to identify the component by it's id
> using some js library (like jQuery) and as a consequence the result of this
> query: $("#quantity.noOfUnits1232") is invalid.
